Abstract

The invention relates to dynamoelectric machine, in particular a wind generator, comprising a stator (1), which is designed as a laminated core and has a winding system, which forms winding heads (16) on the end faces of the stator (1), and a rotor (3), which is designed as a laminated core and which is connected to a shaft (7) in a rotationally fixed manner, wherein the stator (1) and the rotor (3) are arranged in a housing, wherein the shaft (7) is supported by means of bearings (9), which are arranged in bearing shields (8), wherein the laminated core of the stator (1) and/or rotor (3) has axially extending cooling channels (15), wherein the bearing shields (8) form a closed interior together with the housing, said interior having at least one closed inner cooling circuit, wherein the housing has an outer jacket (12) and an inner jacket (19) facing the stator (1) and arranged at a distance from the outer jacket in some sections, wherein the outer jacket (12) and the inner jacket (19) combined form a cooling jacket (11), in particular a liquid cooling jacket, the axial extension of which equals at least the axial extension of the laminated core of the stator (1).
